Nursing Elites

1. A client with asthma develops respiratory acidosis. Based on this diagnosis, what should the nurse expect the client's serum potassium level to be?

• A. normal
• B. elevated
• C. low
• D. unrelated to the pH

Correct answer: B

Rationale: In respiratory acidosis, the body retains CO2, leading to increased hydrogen ion concentration and a drop in blood pH. As pH decreases, serum potassium levels increase due to the movement of potassium out of cells to compensate for the acidosis. Elevated serum potassium levels are expected in respiratory acidosis. Choice A ('normal') is incorrect because potassium levels are expected to be elevated in respiratory acidosis. Choice C ('low') is incorrect as potassium levels rise in this condition. Choice D ('unrelated to the pH') is incorrect as serum potassium levels are directly impacted by changes in pH in respiratory acidosis.

2. A patient who has delivered an 8.2 lb. baby boy 3 days ago via c-section, reports white patches on her breast that aren't going away. Which of the following medications may be necessary?

• A. Nystatin
• B. Atropine
• C. Amoxil
• D. Lortab

Correct answer: A

Rationale: The patient is likely experiencing thrush, a fungal infection, which can present as white patches on the breast that persist. Nystatin is an antifungal medication commonly used to treat thrush. Therefore, the correct answer is Nystatin. Atropine is not indicated for this condition and is used for different purposes. Amoxil is an antibiotic and would not be effective against a fungal infection like thrush. Lortab is a pain medication and is not appropriate for treating thrush.

3. A client needs to rapidly achieve a therapeutic plasma drug concentration of a medication. Rather than wait for steady state to be achieved, the physician might order:

• A. a maintenance dose.
• B. a loading dose.
• C. a medication with no first-pass effect.
• D. the medication to be given intravenously.

Correct answer: B

Rationale: To rapidly achieve a therapeutic plasma drug concentration, a loading or priming dose is ordered. This dose quickly establishes the desired drug level. It is calculated by multiplying the volume of distribution by the desired plasma drug concentration. A maintenance dose, like choice A, is used to maintain the therapeutic level after the loading dose. Waiting for steady state without a loading dose would take five drug half-lives. Choice C, a medication with no first-pass effect, does not directly address the need for rapid attainment of therapeutic levels. While intravenous administration (choice D) offers excellent bioavailability, a single dose by this route may not achieve the desired therapeutic plasma concentration as rapidly as a loading dose.

4. When discussing possible complications of pregnancy with a client, the nurse should explain that all of the following are symptoms of urinary tract infection (UTI). Which of the following is least indicative of UTI during pregnancy?

• A. low back pain
• B. urinary frequency
• C. GI distress
• D. malaise

Correct answer: B

Rationale: Urinary frequency is least indicative of UTI during pregnancy. It is a common minor discomfort of pregnancy caused by pressure of the growing uterus on the bladder. As the uterus rises in the second trimester, there are usually no problems. Frequency may return in the third trimester when the uterus drops into the pelvic cavity. UTI symptoms include low back pain, suprapubic discomfort, and malaise, and are confirmed by laboratory findings. Low back pain, GI distress, and malaise are more closely associated with UTI during pregnancy compared to urinary frequency.

5. The client is admitted with a period of unobserved loss of consciousness and now has an EEG scheduled this morning. What should the nurse implement?

• A. Keep NPO and hold medication.
• B. Hold sedatives, but allow the client to have breakfast and give other medicines.
• C. Administer medications, but hold anticonvulsants.
• D. Give additional fluids and some caffeine prior to the test.

Correct answer: C

Rationale: Prior to an EEG, it is essential for the client to eat to prevent a drop in blood sugar levels. The nurse should hold sedatives but allow the client to have breakfast and administer other necessary medications. Holding sedatives is crucial to ensure accurate EEG results, while providing breakfast helps maintain stable blood sugar levels. Administering other medications, excluding sedatives, is important for the client's overall care. Choices A, C, and D are incorrect because keeping the client NPO and holding medications, administering medications but holding anticonvulsants, and giving additional fluids and caffeine are not appropriate actions before an EEG.
